IMPROVEMENT IN BLIND-STOPS- Specification forming part of Letters PatentNo. 178,739, dated J nne 13, 1876; application filed January 725, 1876.

To all whom it may concern:

Be it known that 1, JOHN L. CRAWFORD, of Michigan City, in the county ofLaporte and State of Indiana, have invented an Improved Blind-SlatFastener, of which the following is a specification:

The object of my invention is to provide a blindslat fastener by meansof which the slats may. be adjusted to and fastened at any angle, evenin the dark; and to this end it consists in a wire hook hung in thelowerend of the slat-rod, in combination with a cast-metal guideplate securedto the lower stile of the blind-frame, which plate has a vertical groovemolded therein, in the bottom of which groove several holes are drilledto receive the point of the hook, which thereby locks the rod andattached slats, all as hereinafter more fully dedescribed and definitelyclaimed.

Figure 1 is a perspective view of a blind whose slats are locked closedby my devices. Fig. 2 is a perspective view of the lower part of saidblind, showing the hook disengaged from the lock. Fig. 3 is a verticalsection through the center of the look.

In the drawing, A represents the frame of a Venetian blind, in which arepivoted the slats B, all of which are", in turn, pivoted to the slat-rodO, in the usual manner. A wire, a, is hung in the lower end of the rod(3, with a square hook turned in its lower end. D is a cast-metal plate,secured to the lower stile of the frame, directly below the slat-rod,and has a vertical groove molded in it, in the path of the hook. Several'holes or sockets, b, are drilled or molded, from the bottom of thegroove, into or through the plate, into either of which holes the hookmaybe inserted to hold the slats at any desired angle. The

groove serves also as a guide for the hook, so

that a person may readily adjust the slats in the dark.

What I claim as my invention is The combination, with the frame A andslats B, of the slat-rod O, pivoted to the center of the said slats, thehooked wire a, hung in the lower end of the said slat-rod, and thecastmetal plate D, secured to the frame, and having a vertical groovemolded in its face, and the series of holes I), all constructed andarranged substantially as described and shown, for the purpose setforth.

JOHN L. CRAWFORD.
